From time to time it happens, that players will be disconnected from mutliplayer races.

Host use P2P mode

Host does not use -autokick

We found out, that the issue happens more often on specific tracks. Examples are Cactus Volt, or Spa-Volt 1. Terminations on stock tracks are very uncommon, it seems it happens more often on custom tracks.

The terminated players are part of the start grid waiting for the countdown to appear, but the game terminates after a few seconds, before the countdown appears. This means the players won't be terminated while the track loads, it happens much later.

Is there a way, where we can find out, what can cause this? (Log files,...)
The terminations are not reproduceable.

That is indeed the case when autokick is enabled. However, the issue at hand occurs even with autokick disabled. From what I recall, this has been a problem even before the autokick feature was implemented, and I suspect (based on prior observations) that it is likelier to occur when either the host (multiple terminations) or a player (one termination) has low bandwidth or a very high ping.
